21267636 divided by 161 
We want to figure out the number of times 21267636 can be divided by 161.

Step 1:
161 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 161

Advancing to step 2:
161 can be fit into 21 0 times, resulting in a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Append the next digit (2) from the dividend to 21 and continue with: 212 / 161

Going ahead to step 3:
If we divide 212 by 161, we get 1 and a remainder of 51.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 161 away from 212, we end up with 51.
Take the next digit (6) from the dividend and append it to 51, then repeat: 516 / 161

On to step 4:
If we divide 516 by 161, we get 3 and a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we take 483 away from 516, we end up with 33.
Grab the next digit (7) from the dividend, add it to 33, then carry on: 337 / 161

Going ahead to step 5:
161 goes into 337 2 times with a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 132.0
Subtract 322 from 337 to get 15.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 161

Moving on to step 6:
161 goes into 156 0 times with a remainder of 156.
The number 0 becomes the next digit in our result. 
Result so far: 1320.0
If we take 0 away from 156, we end up with 156.
Bring next digit (3) of the dividend behind the 156 and repeat the process: 1563 / 161

Going ahead to step 7:
1563 divided by 161 is 9 with a remainder of 114.
Use 9 as the next digit of our solution. 
Result so far: 13209.0
If we take 1449 away from 1563, we end up with 114.
Grab the next digit (6) from the dividend, add it to 114, then carry on: 1146 / 161

Advancing to step 8:
If we divide 1146 by 161, we get 7 and a remainder of 19.
The next digit of our result is 7. 
Result so far: 132097.0
If we subtract 1127 from 1146, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 9:
When dividing 190 by 161, we get 1 with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 132097.1
The remainder is 29 after subtracting 161 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 10:
If we divide 290 by 161, we get 1 and a remainder of 129.
The next digit of our result is 1. 
Result so far: 132097.11
Subtract 161 from 290 to get 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

In conclusion, the division gives 132097.11 with a balance of 0.129.
